I bought a D300 (my first Nikon!) about 3 years ago to photograph the 2010 Olympic games (as a spectator). I have been very happy with it.As I want to get more into wildlife and bird photography, I am currently saving to purchase the Nikkor 200-400mm f/4 VRII lens, which I hope to purchase by the spring. Once I have that lens I will be contacting you about purchasing a Jobu head (Jobu Heavy Duty MK III). I have been impressed with all I have read about their tripod heads.
